The SMB Mailslot parsing functionality in PAM in multiple ISS products with XPU (24.39/1.78/epj/x.x.x.1780), including Proventia A, G, M, Server, and Desktop, BlackICE PC and Server Protection 3.6, and RealSecure 7.0, allows remote attackers to cause a denial of service (infinite loop) via a crafted SMB packet that is not properly handled by the SMB_Mailslot_Heap_Overflow decode.

ISS BlackIce 3.6, as used in multiple products including BlackICE PC Protection, Server Protection, Agent for Server, and RealSecure Desktop 3.6 and 7.0, does not drop privileges before launching help from the "More Info" button in the "Application Protection" dialog, which allows local users to execute arbitrary programs as SYSTEM.

Buffer overflow in blackd.exe for BlackICE PC Protection 3.6 and other versions before 3.6.ccb, with application protection off, allows local users to gain system privileges by modifying the .INI file to contain a long packetLog.fileprefix value.

BlackICE PC Protection and Server Protection installs (1) firewall.ini, (2) blackice.ini, (3) sigs.ini and (4) protect.ini with Everyone Full Control permissions, which allows local users to cause a denial of service (crash) or modify configuration, as demonstrated by modifying firewall.ini to contain a large firewall rule.

Multiple stack-based buffer overflows in the ICQ parsing routines of the ISS Protocol Analysis Module (PAM) component, as used in various RealSecure, Proventia, and BlackICE products, allow remote attackers to execute arbitrary code via a SRV_MULTI response containing a SRV_USER_ONLINE response packet and a SRV_META_USER response packet with long (1) nickname, (2) firstname, (3) lastname, or (4) email address fields, as exploited by the Witty worm.

Heap-based buffer overflow in the ISS Protocol Analysis Module (PAM), as used in certain versions of RealSecure Network 7.0 and Server Sensor 7.0, Proventia A, G, and M Series, RealSecure Desktop 7.0 and 3.6, RealSecure Guard 3.6, RealSecure Sentry 3.6, BlackICE PC Protection 3.6, and BlackICE Server Protection 3.6, allows remote attackers to execute arbitrary code via an SMB packet containing an authentication request with a long username.

BlackICE Defender 2.9.cap and Server Protection 3.5.cdf, when configured to automatically block attacks, allows remote attackers to block IP addresses and cause a denial of service via spoofed packets.
